  • Patent number: 6036037
    Abstract: The invention provides a novel hot fill plastic container with reinforced bands above and below the vacuum panels to prevent panelling (or crease formation under vacuum after cooling) in the label supporting band area. The container has a substantially cylindrical recessed label supporting portion with multiple circumferentially spaced apart vacuum panels. Each panel includes a flat radially recessed central panel face which collapses radially inwardly under vacuum to reduce the volume of the container during cooling of the contents. A like multiple number of elongate posts are defined between the panels and generally reinforce the panel area, however, the top and bottom ends of the posts must be supported or else creases will form in these areas under vacuum. Accordingly, the invention provides for top and bottom cylindrical bands defining the axial upper and lower extent of the panels and posts.

  • Patent number: 5970667
    Abstract: The invention provides a quickly installed and preferably reusable flashing unit for use in roofing or cladding of a building. The flashing is constructed of stainless steel sheet metal for superior corrosion resistance and to withstand rough handling as old roofing material is scraped off the flashing surfaces to prepare it for reuse. The flashing is assembled along joints between assembled flashing components. Each joint includes a resilient gasket between opposing edges of adjacent flashing components. Clips join the components together and resiliently compress the gasket between opposing edges of the adjacent components. After assembly around stacks, openings, edges or other roofing discontinuities, the flashing is incorporated into the roofing in a conventional manner.
